We have a decade or less to radically slow global warming before we risk hitting irreversible tipping points that will lock in catastrophic climate change. The good news is that we know how to slow global warming enough to avert disaster. Cut Super Climate Pollutants Now! explains how a 10-year sprint to cut short-lived “super climate pollutants” -- primarily HFC refrigerants, black carbon (soot), and methane -- can cut the rate of global warming in half, so we can stay in the race to net zero climate emissions by 2050.

Climate Change: Evidence and Causes is a jointly produced publication of The US National Academy of Sciences and The Royal Society. Written by a UK-US team of leading climate scientists and reviewed by climate scientists and others, the publication is intended as a brief, readable reference document for decision makers, policy makers, educators, and other individuals seeking authoritative information on the some of the questions that continue to be asked. Climate Change makes clear what is well-established and where understanding is still developing. It echoes and builds upon the long history of climate-related work from both national academies, as well as on the newest climate-change assessment from the United Nations' Intergovernmental Panel on Climate Change. It touches on current areas of active debate and ongoing research, such as the link between ocean heat content and the rate of warming.

This open access book not only describes the challenges of climate disruption, but also presents solutions. The challenges described include air pollution, climate change, extreme weather, and related health impacts that range from heat stress, vector-borne diseases, food and water insecurity and chronic diseases to malnutrition and mental well-being. The influence of humans on climate change has been established through extensive published evidence and reports. However, the connections between climate change, the health of the planet and the impact on human health have not received the same level of attention. Therefore, the global focus on the public health impacts of climate change is a relatively recent area of interest. This focus is timely since scientists have concluded that changes in climate have led to new weather extremes such as floods, storms, heat waves, droughts and fires, in turn leading to more than 600,000 deaths and the displacement of nearly 4 billion people in the last 20 years. Previous work on the health impacts of climate change was limited mostly to epidemiologic approaches and outcomes and focused less on multidisciplinary, multi-faceted collaborations between physical scientists, public health researchers and policy makers. Further, there was little attention paid to faith-based and ethical approaches to the problem. The solutions and actions we explore in this book engage diverse sectors of civil society, faith leadership, and political leadership, all oriented by ethics, advocacy, and policy with a special focus on poor and vulnerable populations. The book highlights areas we think will resonate broadly with the public, faith leaders, researchers and students across disciplines including the humanities, and policy makers.

Short-lived climate pollutants (SLCPs), including methane, black carbon, hydrofluorocarbons, and tropospheric ozone, have become part of climate policy debates. Discussion has revolved around the potential of their mitigation to slow down global warming in the short term and bring about co-benefits, for instance, for air quality and public health. This book provides the first comprehensive analysis of global SLCP law and governance. A diverse array of contributors delves into the science and evolution of the concept of SLCPs, analyses the legal and governance responses developed under various international and transnational arenas, and discusses selected sectoral case studies.

This book is aimed at graduate students and research scientists interested in gaining a deeper understanding of atmospheric chemistry, fundamental photochemistry, and gas phase and heterogeneous reaction kinetics. It also provides all necessary spectroscopic and kinetic data, which should be useful as reference sources for research scientists in atmospheric chemistry. As an application of reaction chemistry, it provides chapters on tropospheric and stratospheric reaction chemistry, covering tropospheric ozone and photochemical oxidant formation, stratospheric ozone depletion and sulfur chemistry related to acid deposition and the stratospheric aerosol layer. This book is intended not only for students of chemistry but also particularly for non-chemistry students who are studying meteorology, radiation physics, engineering, and ecology/biology and who wish to find a useful source on reaction chemistry.

In the future residential biomass combustion and transport will be important sources for emissions to air of black carbon (BC), as will agriculture and waste management for emissions of methane (CH4). Measures to abate emissions of Short-Lived Climate Pollutants (SLCP) are to varying degrees already in place in the Nordic countries. To reduce emissions beyond current emission projections, additional measures are required. Both technical measures, such as improved technologies, and non-technical measures, such as promoting behavioral changes favoring reduced emissions are discussed in this report. The overall objective of this project is to improve the Nordic emission inventories of Short Lived Climate Pollutants. This report presents results from the third and final phase of the project, an assessment of efficient measures to reduce emissions of Short-Lived Climate Pollutants (SLCP) in the Nordic countries.

Emission inventories of Short Lived Climate Pollutants (SLCP), and especially of Black Carbon are uncertain and not always comparable between countries. Comparable and reliable emission inventories are essential when aiming for efficient strategies and policies for reduced emissions. The overall objective of this project is to improve the Nordic emission inventories of SLCPs. This report presents a summary of results and highlights from four reports produced in the project. The topics cover results from a measurement programme that provided SLCP and PM2.5 emission factors for typical Nordic residential biomass combustion technologies, it covers emission projections and efficient measures to reduce emissions of SLCPs beyond current projections, and also presents results from investigating the potentials for reducing the health and climate impacts of residential biomass combustion.
